Supreme Court Showdown: AR-15 Rights?

The Supreme Court has agreed to decide whether millions of Americans have a constitutional right to own AR-15 rifles — a ruling that could strike down gun bans in nearly a dozen states.

At a Glance

The Supreme Court accepted two cases — Viramontes v. Cook County and Grant v. Higgins — asking whether the Second Amendment protects AR-15-style rifles.
AR-15s are legal in 41 of 50 states, and gun rights advocates argue that widespread ownership puts the rifles firmly under Second Amendment protection.
At least four justices have already signaled skepticism toward assault weapons bans, suggesting the Court may be ready to rule against them.
A ruling is expected by June 2026, and could invalidate bans in Illinois, Connecticut, California, New York, and other states.

The Cases the Supreme Court Just Accepted

The Supreme Court agreed to hear Viramontes v. Cook County and Grant v. Higgins, two cases that ask a single, direct question: Does the Second Amendment protect the right to own AR-15-platform and similar semiautomatic rifles? The cases come from Illinois and Connecticut, both of which ban these rifles. Gun rights groups, including the Firearms Policy Coalition and the Second Amendment Foundation, brought the challenges.

The district court in the Illinois case already sided with gun owners, ruling that the assault weapons ban violates the Second Amendment because there is no comparable historical law that restricted similar firearms. That ruling now heads to the nation’s highest court, where the stakes could not be higher for gun owners and gun control advocates alike.

What the Justices Have Already Said

Several justices have made their views clear — even before accepting these cases. Justices Clarence Thomas, Neil Gorsuch, and Samuel Alito previously said they would have taken an earlier assault weapons ban case. Justice Brett Kavanaugh went further, writing that there is a “strong argument” that AR-15s are in “common use” by law-abiding citizens and are therefore protected. He added that the Court “should and presumably will address the AR-15 issue soon.”

The “common use” standard comes from the Supreme Court’s landmark 2008 ruling in District of Columbia v. Heller, which said the Second Amendment protects weapons that are in common use for lawful purposes. AR-15s are legal in 41 of the 50 states, a fact supporters say proves the rifles meet that standard. Critics counter that Heller also said the government can ban weapons “most useful in military service,” which they argue includes AR-15-style rifles.

The Legal Battle Lines

Gun rights advocates argue the AR-15 is a standard civilian rifle, not a military weapon, and that banning it ignores both the Constitution and the Court’s own precedents. They point to market data showing tens of millions of these rifles in civilian hands. The 2022 Supreme Court ruling in New York State Rifle and Pistol Association v. Bruen added fuel to their case, requiring that any gun law must match the nation’s historical tradition of firearm regulation.

Gun control supporters argue the opposite. The Fourth U.S. Circuit Court of Appeals upheld Maryland’s assault weapons ban, ruling AR-15s fall outside Second Amendment protection because they are excessively dangerous. Groups like Everytown Law point to Heller’s own language, noting the Court said the Second Amendment “is not a right to keep and carry any weapon whatsoever.” The legal divide is real, and only the Supreme Court can now resolve it. A decision is expected by June 2026, and it will set the rules for the entire country.
